Rough Justice [EPUB ebook] 

A tip from a dying cop puts a reporter on a long-closed murder case Easy E.J. Mc Mahon rests six feet underneath the playground at an elementary school in Little Italy. A one-time steakhouse owner with a gambling problem, his troubles started when a struggle broke out for control of a mob family, and E.J. backed the wrong man. E.J. fled to the airport, planning to hop a plane to Wyoming, but was met at the gate by two heavies with badges. As they dragged him out of the airport, he wailed that the men were not real cops. They put him under the cement while he was still breathing. Fifteen years later, newspaperman John Wells gets a call from a dying cop who wants to make a confession. Easy E.J. was wrong: They were cops, working on the mob payroll. Wells goes after the dead cop’s partner, chasing a story so good that it might be worth getting buried alive.
